In its report for the quarter just ending, Company X announces that in some of its manufacturing processes it plans to begin converting from conventional fuels like oil and natural gas, which are rapidly becoming scarce, to synthetic fuels currently under development in the company's laboratories in Europe and the American far west. Implementation of this plan will almost certainly increase the company's expenses, since even if the synthetic fuels are rendered practical for use they can be expected to cost considerably more than conventional fuels.
Which of the following, if true, casts the most doubt on the argument above?
A)Company X's synthetic fuels will not be ready for use in its manufacturing processes for at least a decade.
B)Whatever increased expenses accrue from the development and use of synthetic fuels can and will be passed on to consumers of Company X's products.
C)Company X's manufacturing processes can be adapted to the use of synthetic fuels at little or no expense.
D)In time, the raw materials used to produce Company X's synthetic fuels will become as scarce as oil and natural gas.
E)Long-needed conservation procedures will become practical when synthetic fuels are introduced and will compensate for the higher cost of the fuels.
Isn't both C and E good here?
